Embodiment 1

[0040] A botanical insecticide, its components and their weight ratios are: 7 parts of yam, 2 parts of bitter bark vine, 7 parts of cnidium, 5 parts of dandelion, 3 parts of white chrysanthemum, 4 parts of rose, 1 part of houttuynia 2 parts of Acanthopanax, 5 parts of Panax notoginseng, 3 parts of garlic, 8 parts of camphor leaves, 6 parts of mugwort leaves, 2 parts of lavender, and 7 parts of tangerine peel.

[0041] Preparation method: Measure the raw materials according to the weight ratio, and make dry powder by crushing and mixing. Apply 50kg of this insecticide on the soil surface per mu of land, and wait for sowing after plowing.

[0042] Compared with the corn planted and grown in the same way in the land where the pesticide of the present invention is not applied, the corn sown on the land sown with the pesticide of the present invention: the incidence of diseases and insect pests is significantly reduced, and the growth rate and yield of corn are significantly improv...

Embodiment 2

[0044] A botanical insecticide, its components and their weight ratios are: 9 parts of Chinese yam, 3 parts of bitter bark vine, 10 parts of cnidium, 5 parts of dandelion, 5 parts of white chrysanthemum, 7 parts of rose, 2 parts of Houttuynia cordata 5 parts of Acanthopanax, 7 parts of Panax notoginseng, 5 parts of garlic, 10 parts of camphor leaves, 8 parts of mugwort leaves, 4 parts of lavender, 9 parts of tangerine peel

[0045] Preparation method: Measure the raw materials according to the weight ratio, and make dry powder by crushing and mixing. Every mu uses 45kg insecticide of the present invention. Soybean is directly sown after spraying the insecticide of the present invention on the soil surface.

[0046] The disease incidence of soybean planted on the land applied with the invention is significantly reduced, the root system develops vigorously in the whole growth stage, the self-resistance of soybean is obviously enhanced, and the yield of soybean is increased by 1...

Embodiment 3

[0048] A botanical insecticide, its components and their weight ratios are: 8 parts of Chinese yam, 3 parts of bitter bark vine, 8 parts of Cnidium, 7 parts of dandelion, 4 parts of white chrysanthemum, 6 parts of rose, 2 parts of Houttuynia cordata 4 parts of Acanthopanax, 6 parts of Panax notoginseng, 4 parts of garlic, 9 parts of camphor leaves, 7 parts of mugwort leaves, 3 parts of lavender, 8 parts of tangerine peel

[0049] Preparation method: Measure the raw materials according to the weight ratio, add 50 times the weight of water and stir to extract the active ingredients for 5 hours after crushing and mixing, collect the supernatant, continue the extraction process of the solid residue, repeat the extraction twice, and extract three times The obtained liquid part is the water-soluble active ingredient of the botanical insecticide. Use 50kg of dry insecticide powder per mu.

[0050] Immediately spray and irrigate with the insecticide of the present invention after sow...

Abstract

The invention discloses botanical insecticide. The botanical insecticide comprises, by weight, 1 part to 12 parts of Chinese yam, 0.5 part to 3 parts of angled bittersweet, 1 part to 12 parts of fructus cnidii, 1 part to 10 parts of dandelion, 1 part to 5 parts of feverfew, 3 parts to 10 parts of roses, 1 part to 3 parts of herba houttuyniae, 2 parts to 5 parts of acanthopanax, 4 parts to 10 parts of pseudo-ginseng, 2 parts to 5 parts of garlic, 1 part to 3 parts of camphor tree leaves, 1 part to 10 parts of folium artemisiae argyi, 1 part to 4 parts of lavender and 3 parts to 10 parts of orange peel. The botanical insecticide rapidly plays efficacy, active ingredients are not prone to decomposing, the active ingredients are durable in efficacy, the formula is simple and can be easily standardized, the raw materials are wide in source and low in cost, no chemical pesticide ingredients are contained, and the botanical insecticide is free of pollution and residues and has great application and popularization value.

Description

Technical field: [0001] The invention relates to an insecticide, in particular to a botanical insecticide, and belongs to the technical field of insecticides. Background technique: [0002] Pesticides are an important link in agricultural production and directly affect the economic effects of agricultural production. According to the source, pesticides can be divided into four types: 1. Inorganic and mineral pesticides. Such as lead arsenate, calcium arsenate, sodium fluorosilicate and mineral oil emulsion. Such insecticides generally have low drug efficacy and are likely to cause phytotoxicity to crops, while arsenic is highly toxic to humans. Therefore, most of the organically synthesized pesticides have been eliminated. 2. Botanical pesticides. There are about 1,000 kinds of plants in the world that are more or less toxic to insects. Pyrethrum, deer vine and tobacco are widely used. In addition, some plants also contain active substances similar to juvenile hormone,...
